Referring tothe drawings, a cylindrical body member or external container' is shown at I` pro'- vided with a lower wall 2 having a fluid' outlet connection 3 and a removablexupper'wall orh'ead 4 secured to the member I throughr` the agency of a plurality of stud bolts 5 and wing nuts B. 'Ihe bolts 5` are preferably secured to the container I as by casting said container about the knurled lower ends 5a of said bolts; according to conventional practice. A suitable gasket member 1 is preferably provided at the upper end of the container I in position to beV engaged by the l head member 4 to effectively sealthe external container, said gasket being conveniently clisposed in a suitable annular recess 1a inthe lower surface of the head I. Av liquid discharge member is provided within the container I and may comprise a cylndricalsleeve II provided with a plurality of perforations IIa in the side walls thereof asv shown particularly in Fig. 3, and extending axially upwardly withinl the cylindrical space defined by the side walls of the container I to a pointvadjacent the upper end of said container. The perforate sleeve II is preferably disposed' about a suitable supporting member such as an upwardly projecting cross shaped member I2 provided' with recesses or .passages I2a extending along the length of said member.

collar 2a formed in said wall and rolled the outer edge of a peripheral bead Ila formed on said foot member. Where the purifying device is not subjected toA very great pressures, the supporting member |2 may be dispensed with,

and the sleeve Il secured to the foot member il in any suitable manner. `The upper end of the member I2 may be 'provided with a projecting portion Il of reduced diameter and carrying a washer or the like engaging the upper end of the sleeve Il, the outer end of the. projection Il being riveted over to secure'the washer i5' in position. A plurality y of openings I6 are pro-M vided in the foot member Il interiorly of -sleeve and establishing communication between the recesses |2a and the liquid discharge connection 3, said openings constituting the only means for outow of liquid from theinteriox` of the container to the discharge connection I. A suitable drain plug or the like may be provided as at |1 at the-lower wall of the container I if .The .removable purifying. element 'may' comprise a cylindrical container 2| provided with a: closed upper end wall 22j provided with a bail 23- in position to be grasped manually when the head l. is removed from the device. 'I'he lower ywall 24 having a closed upper end 25 and extending through an opening 26 at the center of an inner wallA member 21 atfthe lower end of the container 2|. The wall member 21 is secured to the side walls of the container 2| in any suitable manner as by means of a conventional form of roll seam provided. for the ends of a tin can.l Such a construction is shown in larger scalepdetail in Figs. 4 and 5. 'I'he lower end ofthe sock 24 is bifurcated or split into a plurality of strips 24a which are stretched or splayed outwardly over the rimf21a of the inner wall 21 and secured to said wall through thev agency of an outer wall member 28 which is secured to the rim portion y21a of the innex` wall 21 in the same manner as said inner wall is secured to the side walls 2|a of the container 2|. A suitable opening 29 is provided at the center of the wall in line with the opening above described and a portion of the metal of the wall 2l may be rolled upwardly within .the sock 2l,`as shown at 3|, to secure said sock firmly at the position of the aforesaid openings 2l and 29. Other forms of construction may, of course, be employed for connecting the llower end of the pervious tubularmember 2l to the lower end wall of the container 2|. Y 'Ihe interior of the container 2|, that is, the

`space between the sock A24 and the side walls 2|a of said container, is preferably substantially completely filled with a mass of purifying material which may comprise a body of fibrous material such as paper pulp or a porous mass of decolorizing material such as fuller's earth or the like, or mixtures of such materials, dependent upon the particular purifying problemy at hand. 'Ihe side wall 2 la of the container 2| is provided with suitable liquid inlet means suchas a plurality of openings 32 arranged in a plurality of rows or in any over lil.

openings 32 are preferablydisposed adjacent the,l

upper end of the container 2l. The mass of purivfying material, designated at Il, is preferably 'spaced from the side wall 2|a of said container in some suitable manner as, for example,v through the agency of a helical wire spacer Il and a screen member 35, to allow free access of the incoming liguiddto the full length of the purifyingbpdy. In the eifent that a clay orfcompa'r'abfejniaterial is employed for the purifying body, "I' preferably 'provide a closely woven or fine-grained fluidpervious membrane 3l interiorly of the screen II topi-event dusting of the material from the body Il. The membrane It may be formed oi' fabric u desired, anhugn I have found a thin, pervlouscellulosic material comparable to the sheet material obtainable lunder the trade name Kleenex" to be'hi'ghly advantageous when an oleaginous liquidistobe passed through thelpurifler. .A thin sheet of such a cellulosic materiallmay be secured` in place against the screen 35 before' the.

interior. of the container is filled' with theV body 33,

as'by'dampening 'the screen 35' with a suitable adhesive such as sodium silicate solution, pressing the membrane 36 against the inner surface of said screenand allowing the adhesive to dry.

The container is provided with a liquid inlet connection 4| opening into the interior of said container as at 42, and rsuitable meansgare `preferablyprovided for varying the size of the inlet open ing,las` by means of a screw 43 threadedly disposed in the sidewall of thecontainer, in position'to extend across any desired portion of the openingI I2. A suitable lock nut or the like is preferably'provided as at `Il to secure the screw 43 1n an estasnshedposition. The nquidxnlet connection Iis preferably located' adjacent the. l

upper end of the container I, somewhat afterthe manner shown, but th specific location of this inlet is purely a matterof choice, as will be ap`v parent to one skilled in the art.

'In assembling the removable purifying element,

I may utilize a conventional tin can closed at one end and` open at'the other, an openingV 26 .being provided for the closed end of the can, which closed end will constitute the wall 21.. The sock 2l is then inserted within the opening 26 and the open end thereof splayed out over the said lower wall after the manner shown in Figs. 3 and 5, a center-perforated conventional can lid 2l being then rolled into engagement with the rim of the can over the splayed ends of the sock, to engage the rim 21a of the wall 21,.a'nd'the central portion of said lidv being rolled inwardly as above described to securely' engage the sock at the position of tle openings 28 and 29. A mandrel may then be inserted within the sock 2l, simulatingthe position of the sleeve I, the helical support or spacer Il placedin position against the side wallf2|aY of the can, and the screen 35 and the membrane 3B placed in position againstthe spacer '34. :The space between the membrane I6 and the `sozl: 24 is then filled with the purifying body 33, and the upper wall 22 then placed over the openend of the can and rolled into .-secure engagement with-the upper edges of thev side wall 2|a ln'fthe same manner as the ordinary tinfcan is capped in a canning operation. 'Ihe mandrel mayvthen be withdrawn, and, assuming the holes 32' tohave been previously formed in the side wall 2| of the can, the purifying element isl ready for use.

'I'he axial length `of the container 2| is so selected with respect to the' interior axial length ...ram

of the container I as to'prov'ide sealing 'engagement with the lower wall 28 of the container 2l against a gasket member 46 which is ,in turn forced'into firm engagement with the upper sur'- 'face ofthe foot m'ember I3when-v the head 4. is

forced downwardly totake up-on the gasket" 1, al suitable shoulder means such" as' a bossorf projection 41 being'provid'ed'on the lower face ofthe y wall 4f in position to engage the upper wall 22. ofA

the can 23I` to force the purifying element downwardly into sealing engagement with'` thef gasket v 461 Minor variations in theV axial length' of. theI container 2I are readily accommodated bythe resilienceof the head 22;-

In the operation ofthe device, theliquidltobe purifiedl is admitted' at 42, enters the purifying-- element through the openingsl2?whenceitlmay@y .in passing inwardly toward the`r sock' 24",y andl the -puried liquid enters the space withinztlie-sleeve il through the openings I=I'aandi isfwithdrawn"4 from the" device through 'the openings I6: and

connection 3; Whenit is' desired to2 replacer an exhausted purifying element it is merely necesr` sary to stop the flow ofli'quidrremove theA wing nuts 6, lift the' head 4 from the container I', grasp the purifying element by means of the bail 2'3and liftY the same from the container" I. The new purifying element is placed within the container I by a reverse procedure, and the entire'operation of removing and replacing the purifying element may be carried out in less than a; mnutes time. The device is primarily adapted for' use on internal combustion engines, and the facilerepl'acement of the purifying element makes it possible to remove and renew the purier without the aid of skilled labor. A suitable bracket or the like may be provided as shown at 5I, to'secure the purifying deviceto a suitable supporting structure adjacent the engine with which the device is associated, as will be apparent to one skilled in the art.

In the above specific description of the present device I have considered that the cylindrical container I is disposed substantially vertically in use. It will be appreciated that the device might equally well be disposed at an angle to the vertical 'Without departing from the spirit of the invention. Furthermore, while the liquid discharge member II is shown as extending upwardly from the lower Wall of the container I, it will be appreciatedthat the construction may be inverted, or the member II may be secured'to the upper ,wall 4 of the device, within the contemplation of this invention. 4In general, it is more convenient to provide both the liquid inlet and outlet connections on the relatively fixed portion of the device, as upon the container I as shown, whereby it is not necessary to remove such a connection in the operation of replacing the removable purifying element. The removable purifying element is most advantageously formed of circular cross-section, whereby conventional canning machines may be utilized in assembly thereof, but at the same time it will be realized that the specific cross-- sectional configuration of the element is a matterV of choice, and as far as the operational characteristicsof the device are concerned, a crosssection other than circular may be employed.

In like manner, `the shape of the external con-` tainer is not necessarily restricted to cylindrical, although in view of the factthat the device is ordinarily required to withstand a modicum of internal pressure across-section o! circular shape lprovideseconomies@irifabrication, as will be apparent to onerskilledinrthe artv oflmetalworking.
